Olefin-metathesis-based synthesis of furans by an RCM/deprotonation/ phosphorylation sequence and their Diels-Alder reactions

Butenolides, obtained by ring-closing metathesis (RCM) of acrylates, undergo quantitative deprotonation with amide bases. Trapping of the resulting anions with electrophiles, for example, chlorophosphates, give furans. Subsequent Diels-Alder reaction and acid-catalysed rearrangement of the resulting oxabicyclonorbornadienes give substituted benzenes.
